What I'm doing is the following:

Incoming: I'm using the --ip-addr to bind() to a particular local IP address
(this affects where I see incoming packets)

Outgoing: I'm using an ipfw firewall rule to push packets with this local
address in the source field out along a particular interface.


If you're using Linux, you could modify the library to do a setsockopt()
with SO_BINDTODEVICE, but I think this is a Linux-only option. Might be
useful for you though.


Cheers,
-S.
